Ultra-high b-value Diffusion-weighted Prostate MR is gaining more attention in medical imaging, due to the non-invasiveness of imaging and to better contrast of malignant tissues as the lower diffusivity of water molecules can enable early diagnosis of cancer. The main drawback of MR at ultra-high b-value is the poor resultant SNR of the reconstructed images. We propose to improve the image quality of the prostate data acquired at b=2000 s/mm2 using a machine learning based reconstruction approach. Significant increase in signal intensities in the central gland and peripheral zone of the prostate was observed in healthy subjects.
